Three pressure ranges = performance and
versatility

The three pressure ranges of the WPS500X allow for accurate
measurement and analysis of many automotive pressures including
cylinder compression, fuel pressure, intake manifold vacuum and
even pulses from the exhaust.

Range 1

Running compression waveform

The first range gives you high resolution and accuracy for
high-pressure tests such as cranking and running cylinder
compression or fuel pressure testing. Not only is this test a
great way for you to find compression issues, but it is also an
excellent way for you to identify cam timing issues such as
jumped timing belts and stretched timing chains — this is
especially useful on multi-cam engines that may not have a cam
sensor on each camshaft.

Range 2

The second range measures from -15 to 50
psi (approximately -1 to 3.45 bar).
This range is ideal for vacuum tests and fuel system tests. When
testing these systems you will find the zoom function is
especially useful as it makes it easy to analyse the valves
operating with the vacuum waveform, or the injectors through the
fuel waveform.

snap-throttle

Range 3

With the third range you can measure
-5 to
5 psi (approximately -0.34 to 0.34 bar).
This setting is sensitive enough to allow you to analyse small
pressures or pulses such as pulses from the exhaust.

Built-in zoom function for enhanced analysis

Using the zoom function to showintake
valve pulses (ChA)

The zoom function operates by removing all of the voltage
from the signal below 100 Hz and then multiplying the remaining
signal up to 100 times. For example: Let's say your transducer
is connected to the intake manifold vacuum on a running engine
at idle with the transducer set to mode 2 (-15 to 50 psi) and
the waveform on your PicoScope is at -9 psi.
The fluctuation in the signal caused by the valves opening and
closing versus atmospheric pressure forcing air into the
manifold will be visible, but will only make up a small portion
of the overall signal. Selecting the zoom function will bring
the waveform up to the zero line and the fluctuations will be
magnified making analysis of this component of the signal much
clearer.

Nothing compares to the WPS500X

It is not unusal to require a different pressure transducer
for each diagnostic test you want to run. The WPS500X eliminates
this need by giving you one ultra-high resolution transducer
that can be used for a multitude of automotive diagnostic
applications. With three pressure ranges, a zoom function,
pressure relief valve and a rechargeable Li-Po battery all
enclosed in a durable housing the WPS500X is the cost-effective
answer to pressure analysis.

When price, performance and versatility matter, there is
nothing that compares to the WPS500X Automotive Pressure
Transducer.

This brass bi-conical universal vacuum adaptor can
be used to allow the WPS and FirstLook Sensor hoses
to be connected to various sizes of smaller vacuum
hoses within an engine bay. The adaptor fits vacuum
tubes with internal diameters ranging from
approximately 8.5 mm or 5/16 in, to 2.8 mm or 1/8
in.

The TA083 fuel hose is designed specifically for
use with the WPS500X pressure transducer, with a
strong construction to ensure safe and accurate
operation. The hose is terminated at one end with a
Foster connector to fit the WPS500X, and at the
other end with a Schrader valve to fit standard fuel
rails.
